Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline maintenance and plugging, and in particular relates to an oil and gas gathering and transportation pipeline maintenance and plugging device. Background Art

[0002] When repairing oil and gas gathering and transportation pipelines, repair welding is a common method for repairing small cracks, small holes or local corrosion defects on the pipeline surface.

[0003] When a pipeline suffers from large-scale corrosion, rupture, or severe deformation that cannot be solved by simple repair methods, it is necessary to replace some pipe sections. First, the length of the pipe section to be replaced must be determined and cut at the appropriate location on the pipeline. When cutting, care must be taken to avoid sparks to prevent oil and gas combustion. The new pipe section is then installed in place. The connection between the new pipe section and the original pipeline can be made by welding or flange connection. However, this method requires the entire pipeline to be shut down for a certain period of time, which will affect normal production and life. To address the above problems, a maintenance and plugging device for oil and gas gathering and transportation pipelines has been proposed. Utility Model Content

[0006] Furthermore, the fixing rings are connected by bolts.

[0007] Furthermore, a sealing gasket is symmetrically fixedly installed in the fixing ring.

[0008] Furthermore, the surface of the airbag is coated with a protective layer and a wear-resistant layer.

[0021] An oil and gas gathering and transportation pipeline maintenance and plugging device comprises a pipeline body 1, on which a pipeline maintenance and plugging assembly is provided;

[0022] The pipeline repair and plugging assembly includes a fixing ring 2 symmetrically arranged on a pipeline body 1, with a protrusion 3 fixedly mounted on the fixing ring 2, and the protrusion 3 and the fixing ring 2 are connected to each other; an air pump 4 is fixedly mounted on the protrusion 3 on one side, and the air pump 4 is connected to an air supply pipe 5, and one end of the air supply pipe 5 extending into the pipeline body 1 is connected to an air bag 6; a connecting pipe 7 is fixedly mounted on one side of the protrusion 3, and the connecting pipe 7 is connected to a threaded pipe 8, and a branch pipe 9 is threadedly connected between the threaded pipes 8;

[0023] From the above description, it can be seen that the fixing ring 2 is installed in the middle of the damaged position of the pipe body 1, and a hole is opened at the corresponding position of the pipe body 1 to ensure that the airbag 6 can enter the pipe body 1 in advance. After installation, the power of the air pump 4 is turned on and the airbag 6 is inflated. After the inflation is completed, the airbag 6 squeezes the inner wall of the pipe body 1 to achieve the sealing of the pipe body 1. Then remove the sealing material on the threaded tube 8 and connect the branch pipe 9 to ensure that the branch pipe 9 can transport a certain amount of materials for production and life in an emergency.

[0024] As a technical optimization solution of the present invention, the fixing rings 2 are connected by bolts;

[0025] It can be seen from the above description that the connection through bolts can meet the requirements of rapid fixation and disassembly between the fixing rings 2.
